Abstract

An outer enclosure contains two cylinders which are perforated over half their periphery and rotate with respect to each other in order to obstruct some of the holes; a piston, provided with valves, progressively obstructs the holes, in order to confer progressive damping; mutual rotation of the two cylinders brings about adjustment of rigidity, while a mass M with a ratchet which causes the intermediate cylinder to rotate opens some of the holes corresponding to dips or projections in the ground. <IMAGE>
